ISAAC SHEROK, OF FLAT ROCK, OHIO.

WRENCH.

SPECIFICATION forming part of Letters Patent N 0. 585,125, dated June22, 1897;

Application filed April 19, 1897.

To all whont it ntrrq concern.-

Be it known that I, ISAAC SHERCK, a citizen of the United States,residing at Flat Rock, in the county of Seneca and State of Ohio, haveinvented certain new and useful Impro vements in Wrenches; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters of referencemarked thereon.

The present invention has reference to that class of wrenches in whichare employed a stationary jaw and a pivoted jaw held in its adjustedposition by a spring-actuated pawl engaging with the teeth upon the barof the stationary jaw.

It is the purpose of the invention to improve the construction of theabove class of wrenches whereby they will be more effective in theiroperation, giving a more perfect grip, as well as possessing thenecessary strength and durability.

The invention consists in a wrench constructed substantially as shown inthe drawings and hereinafter described and-claimed.

Figure 1 of the drawings is a side ele'vation of the wrench, partly insection; Fig. .2, a detail perspective view of the pivoted jaw; Fig. 3,a similar view of the sliding head; Fig. 4, a detail sectional viewtaken on line x 00 of Fig. 1.

In the accompanying drawings, A represents the usual bar of a wrenchprovided with ratchet-teeth upon its inner side and terminating in ashank a, upon which is fitted the handle B, which is held thereon by ascrewnut 19, engaging with the projecting screwthreaded end of saidshank. The bar A has a stationary jaw O, disposed at an obtuse angle tothe length of the bar A, and upon its inner face has suitablegripping-teeth of the usual construction. Between the jaw C and the barA is a web 0, which joins the two together and forms seats upon itsopposite sides to receive the shoulders cl upon the inner sides of arms6, which project at substantially right angles to thejaw, the platesbeing pivoted to the web by means of the screw-threaded pin f. Theplates e have eX tensions g upon the opposite side of the jaw D, andbetween these extensions is a curved Serial No. 632,723. (No model.)

slotted flange h, which is held between the extensions by a pin 0',passing through the same and through the slot of the flange, therebyforming a connection between the jaw D and the sliding head E. Thissliding head E has the usual loops is, through which the bar A passes,and is provided with a spring-actuated pawl F to engage with theratchet-teeth on the barA. A coiled spring n bears against the engagingend of the pawl F to retain the same in engagement with theratchet-teeth on the bar A, and the opposite end of the pawl terminatesin a bearing extension Z for receiving the presser-foot G.

Then it is desired to use the wrench, the presser-foot G is depressedwith the thumb or finger, which will raise the engaging end of the pawlF from contact with the ratchetteeth of the bar A. This will allow thehead E to be moved on the bar A, which carries with it the movable jawD, said jaw moving on the arc of a circle by reason of the curved slotin the flange h, which acts as a cam in connection with the pin 1'. Whenthe jaws are in operation, the strain of the jaw D will come 011 thecurved bearings m, formed on the head- E, and also the plates 6 willbear against the shoulders formed by the web 0 with the juncture of thejaw O and bar A. This forms a very perfect and strong reinforce for themovable jaw, giving it both strength and durability, that are necessaryin,

heavy work, as well as providing compactness and preventing the jaw fromspringing.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

1. A wrench consisting of a ratchet-bar and stationary jaw disposed atan obtuse angle thereto, a head slidable uponthe bar, a springactuatedpivoted pawl to engage with the ratchet-teeth on the bar and means foroperating the pawl, and a pivoted jaw connecting with the head by meansof curved slot and pin, substantially as and for the purpose set forth.

2. A wrench consisting ofa ratchet-bar, a stationary jaw thereondisposed at an obtuse angle to the bar, a web connecting the bar withthe jaw, a movable jaw having plates at substantially right anglesthereto and having flanges which fit down against the faces of the weband pivoted thereto, a'slidable head upon the bar, a spring-actuatedpivoted pawl connected to the head and adapted to engage the teeth uponthe bar, and means for connecting the movable jaw to the head,consisting of a flange having a curved slot and a pin extending throughthe slot and through extensions of the movable jaw, substantially as andfor the purpose specified.

3. A wreneh consisting of a ratchet-bar having a stationary jaw disposedat an obtuse angle thereto, a pivoted jaw, a head slidable upon theratchet-bar, a spring-actuated pawl having a bearing extension andcarried by said head, a presser-foot adapted to engage with the bearingextension to bring the pawl out of engagement with the teeth upon thebar, and means for connecting the movable jaw with the head, consistingof a flange having a curved slot to act as a cam, and a pin acting inconnection therewith, substantially as and for the purpose described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

ISAAC SHERCK.
